OdGeExternalCurve2d Class
Syntax
C++
class OdGeExternalCurve2d : public OdGeCurve2d;

This class represents, as OdGeCurve2d curves, 2D curves whose definitions are external to the OdGe library.

OdGeExternalCurve2d curve instances can be treated as any other OdCurve2d. 

You can access the OdGeExternalCurve2d as a corresponding native OdGeCurve2d curve, if such a corresponding curve exists, or you may (more efficiently) access the external data in its native form. 

One example of using OdGeOdGeExternalCurve2d is to represent an ACIS curve. 

Corresponding C++ library: TD_Ge
